You mean this?
"The Andreus' allegation was not supported by any of the eight other people present, including Armstrong's doctor Craig Nichols, or his medical history"
You might not like that being on Lances wiki page but it's source is Velonews.

"And in a sworn affidavit, Dr. Craig Nichols – one of the doctors treating Armstrong at Indiana University Medical Center – said he and other medical personnel visited with Armstrong that day about his medical history before he started chemotherapy, and no such admission was ever made in his presence.
Now the chair of hematology-oncology at Oregon Health and Sciences University, Nichols said that Armstrong "never admitted, suggested or indicated that he has ever taken performance-enhancing drugs. Had this been disclosed to me, I would have recorded it, or been aware of it, as a pertinent aspect of Lance Armstrong's past medical history as I always do."
"Had I been present at any such 'confession,' I would most certainly have vividly recalled the fact," Nichols, a member of the Scientific Advisory Committee of the Lance Armstrong Foundation, continued. "I would have recorded such a confession as a matter of form, as indeed, would have my colleagues. None was recorded."
That's the other side of the story.
